Software Engineer III (AI)

iXsystems DBA TrueNAS, Inc (“TrueNAS”)•Campbell, CA

About The Position

TrueNAS is redefining enterprise storage by delivering proven data resilience, performance, and flexibility without the complexity or constraints of legacy solutions. As the most deployed storage platform in the world, TrueNAS already powers critical data storage infrastructure for businesses, research institutions, and government agencies across 200+ countries and millions of users. Our mission is simple: to become the most trusted name in data storage. Originally founded in Silicon Valley in 2002 under the name iXsystems, TrueNAS is a profitable, independent company with a culture rooted in trust, curiosity, technical excellence, and continuous improvement. Whether you work remotely or on-site, you’ll be part of a team that values collaboration and meaningful impact - where people come before profit, and bold ideas drive the future of data infrastructure. If you’re ready to help shape the future of enterprise storage, we’d love to connect. As a Software Engineer III (AI), you'll build the AI infrastructure that runs natively on TrueNAS, turning a storage platform into an active participant in modern AI workflows, rather than a passive backend. This role typically suits engineers with a few years of varied software engineering experience, often around 3-5 years, and sits at the intersection of ZFS internals and applied ML infrastructure.

Requirements

Strong backend engineering fundamentals. You're comfortable in Go, Python, or C and can pick up the others. You've shipped systems that handle real load.
Hands-on experience with vector search, embedding models, or RAG pipelines in production. You understand the difference between a demo and something that holds up under scale.
Familiarity with GPU programming or GPU-accelerated libraries (CUDA, cuVS, DALI, TensorRT, or equivalents).
Comfort working close to the storage and filesystem layer. ZFS experience is a strong plus; if not ZFS, then equivalent depth in another filesystem.
Experience with Agentic Engineering. You should have a solid understanding of how to use AI-first development workflows for most common engineering disciplines.

Nice To Haves

Background in time-series anomaly detection or ML-driven observability.
Contributions to open-source storage, ML infrastructure, or MCP-related projects.
Experience with model quantization (4-bit, BitNet) and on-device inference constraints.

Responsibilities

On-array vectorization pipelines. Design and implement the systems that generate embeddings for data living on TrueNAS - including per-file sidecar generation driven by filesystem events and snapshot-time index compilation.
GPU-accelerated inference. Build out the inference path using cuVS/CAGRA and similar libraries, targeting NVIDIA L4/A2-class GPUs in appliance form factors. You'll make decisions about model selection, quantization tradeoffs, and how inference workloads coexist with storage workloads on the same hardware.
AIOps. Develop anomaly detection, predictive maintenance, and log analysis systems that consume the telemetry TrueNAS already produces. The goal is fleet-scale insight that's actually useful to operators, not dashboards full of noise.
MCP and adjacent integrations. Extend our MCP surface so TrueNAS systems are first-class citizens in agent-driven workflows - both as data sources and as systems agents can operate on.
This prepares you for Software Engineer IV (AI), broadening your scope and influence over the AI platform direction.
